MIDDLE-BREAKER PLOW.

Application filed Gctober 25, 1922. Serial No. 586,752.

Middle breaker provided with blades to hold eral movement plow body against movement of its point up or down when cutting a furrow, the blades and heel slides thereby co-operating to steady the operations of the plow bodies, to accomplish which is the purpose of these rudders.

These rudders have hitherto been constructed of a number of separate parts bolted together and secured to the beam and moldboards in a more or less loose manner. In short, the construction hitherto has been weak and frequently became loose, necessitating frequent attention.

This invention has for its purposes the provision of a rudder which will be of very simple and durable construction and in use will possess maximum rigidity, and also one which will serve as a means through which the handles will be rigidly united to the beam.

To this end the invention consists in certain novel features in the construction and correlation of the parts substantially as hereinafter set forth and particularly claimed.

In the accompanying drawing illustrating the invention z- Fig. 1 is a perspective View of part of a middle breaker plow provided with my novel construction of rudder, viewed from a point rearward-of the moldboards: and

Fig. 2 is a plan view of the underside of the same.

Similar characters of reference denote corresponding parts in both figures.

The beam A is of ordinary construction and to its lower end a frog B of the usual or any suitable construction is secured in the usual way. The double moldboard C and point or share D, likewise are of the usual construction and are secured to each other and to the frog in the usual or any suitable manner. The handles E similarly need not differ from the ordinary plow handles, but their manner of attachment to the plow body is peculiar to the present invention as this is effected through the rudder which constitutes my invention.

This rudder is formed of two body members G, G, a rudder blade H mounted between and projecting below the lower surfaces of the same and a heel slide I secured plows are commonly rudders which comprise the plow bodies against latand heel slides to hold the to the rear ends of the body elements G, G and stiffening the structure well as forming the lower surface of the rear end of the rudder.

The side members G G have their forward portions 10 arranged to lie on opposite sides of the lower end of the beam A with their forward edges substantially in contact with the rear surface of the frog B. These forward portions 10 are in a plane vertically outside the planes of lower rear portions 11, 11 of the members G G, thus forming shoulders 12, 12 to engage the rear surface of the beam A. Their lower rear portions 11, 11 are arranged to receive the rudder blade H between them, and also to receive between them the stem 22 of the heel slide I. The upper rear portions 13, 13 of the members G, G are arranged in a diverging relation to lie against the inner surfaces of the lower ends of the handles E E.

The rudder is secured to the beam A. by bolts 15, 15 extending through the portions 10, 10, and to the handles E by bolts 16, 16 extending through the portions 13, 13, whereby the handles are rigidly secured to the beam through the medium of the rudder. To reinforce the connection of the rudder to the handles a spacing member 17 is secured to the members 13, 13 and handles E by the bolt which secures the handles to said members; and to stiffen the portions 13, 13 and thereby further reinforce the connection of the handles to the beam through the medium of the rudder, said portions have their rear edges formed with flanges 18, 18 which e tend from the upper end of the members 13 to the beam A.

The blade H may be of usual construction and is pivotally mounted on a bolt 19 so as to be adjustable. It is held in adjusted position by the bolt 20 which extends through a slot 21 in the blade, the slot per mitting the adjustment of the blade. The heel slide I is provided with a stifi stem 22 which is secured between the rear ends of the portions 11 ofthe members G, G by bolts 23. Obviously the bolts 19, 20' and :23 secure the members G G to each other and serve to clamp the blade H and heel slide etween them. In practice the stem of the heel slide is preferably formed with slots through which the securing bolts 23 pass, to permit vertical adjustment of the slide. It Will be noted that the construction throughout is strong and rigid, and that the need. for braces to connect the horizontal or ground engaging portion of the rudder to the handles is obviated.

Having thus set forth the purposes and construction of my invention and certain of the important advantages, what I claim is 1. A middlebreaker plow comprising a beam and a rudder whose body substantially engages, and is rigidly secured to, both sides of the beam, and handles rigidly secured to the rudder and rigidly united to the beam thereby.

2. A rudder for a middlebrealrer plow, comprising body having its forward end formed to receive the plow beam and to be rigidly secured at its opposite sides thereto, said body provided with elements to engage the respective plow handles and to be rigidly secured thereto, whereby the beam and bandles will be rigidly united by said rudder; the rudder also comprising a rudder blade carried by said body.

3. A rudder for a middlebreaker plow, comprising a. body whose lower end forms a ground engaging shoe and whose forward end projects upwardly from said shoe and is provided with spaced side members to form. an open channel. with side walls to receive the plow beam between them and with elements projecting toward each other from said side walls to substantially engage the adjacent part of the beam, said body also having elements rigidly connected therewith to engage the respective plow handles, means to secure the side walls rigidly to the plow beam and the last mentioned elements rigidly to the respective handles and a rudder blade carried by the body.

t. A rudder for a middlebreaker plow, comprising spaced body members, a rudder blade and a heel slide: said body members being relat'vely arranged at their forward ends to receive the plow beam between them and having at their said forward end extensions to engage the plow handles, respectively; the body members also having rearward extensions to which the rudder blade and heel slide are connected; and means to secure the forward portions of the body members to the plow beam and the forward extensions to the plow handles.

5. A middlebreaker plow, comprising a beam, handles and arudder, said rudder including a body and a blade pivoted to said to receive and partially body, and said body having spaced side members formed to provide in the lower part of the forward end of the rudder a channel embrace the lower end of the beam and above its said channeled portion with upward extensions to engage the respective handles and means for securing the channeled portions and upwardly extending portions of the rudder rigidly to the beam and handles respectively, to provide a strong and rigid construction and one in which the handles are secured to the beam through the medium of the rudder.

6. A mi ddlebrealzer plow, comprising a beam, handles and a rudder, said rudder being rigidly secured to the beam and handles and securing the latter to the beam, the rudder also having rearward extensions, a

guide plate arranged between said exten- SEOHS, and a slide heel having a rigid stem also arranged between the extensions at the rear end of the rudder and rigidly secured to and stillening said extensions.

7. A middlebreaker plow, comprising a beam, handles and a rudder, said rudder having spaced side members formed to proride in the lower part of the forward end of the rudder a channel to receive and par embrace the lower end of the beam and above its said channeled portion with upward extensions to engage the respective handles and means for securing the channeled portions and upwardly extending portions of the rudder rigi lly to the beam and handles respectively, the rudder also having lower rearward extensions, a guide plate a ranged between said extensions and a slide heel having a rigid stem arranged between the extensions at the rear end of the rudder and rigidly secured to and stifl'ening said extensions.

8. In a middle breaker plow the combination with. the beam, of a rudder comprising a body which substantially engages and is rigidly secured to both sides of the beam and is provided with rearward extensions, a'slide heel having a rigid stem arranged between said extensions and at the rear end of the rudder and rigidly secured to and stiffening said extensions, and a guide plate also arranged between said extensions and between the slide heel and beam-engaging portion of the rudder.

In testimony whereof I affix my signature.
